No Faults
N/A
N/A
N/A
0010
AC Frequency Low
S
This fault indicates that the Utility
grid frequency is below or fell below
the minimum allowed value of
59.3 Hz for greater than 6 cycles.
This fault is auto-clearing. Once the
Utility grid frequency has recovered
within the acceptable operating
range, the PV225S
will qualify the
value and automatically clear this
fault and resume normal operation
after 5 minute delay period.
•
Utility grid frequency
fell below the allowable
limit
0011
AC Frequency High
S
This fault indicates that the Utility
grid frequency is above or rose above
the maximum allowed value of
60.5Hz for greater than 6 cycles. This
fault is auto-clearing. Once the Utility
grid frequency has recovered within
the acceptable operating range, the
PV225S
will qualify the value and
automatically clear this fault and
resume normal operation after
5 minute delay period.
•
Utility grid frequency
rose above the
allowable limit
0012
AC Voltage Low
S
This fault indicates that the utility
grid voltage is below or fell below the
minimum allowed value of 88% of
nominal Vac for greater than
2 seconds, or 50% of nominal VAC
for greater than 6 cycles. This fault is
auto-clearing. Once the Utility grid
voltage has recovered within the
acceptable operating range, the
PV225S
will qualify the value and
automatically clear this fault and
resume normal operation after
5 minute delay period.
•
Utility grid voltage fell
below the allowable
limit
•
Fuses F1, F2, F3, F7, F8
or F9 blown
•
P1001 on CCU2 is
loose or disconnected
